The impact screwdriver bits are made of specially heat-treated S2 steel, which offers high strength and hardness (HRC60-61). They are durable, anti-bending, and feature a black phosphate finish for enhanced corrosion resistance, adhesion, and surface hardness.The head of the screwdriver is magnetized for easy use. Phillips bits designed with magnetism can stably absorb the screws vertically or tilted and easily fix the screws, especially in a small space, which can make it more convenient to complete the work. Precision CNC machined cross head, precise appearance, reduces head wear during high-intensity tightening operations.
